Abstract
An apparatus includes a photonic integrated circuit having an optical phased array, where the optical phased array includes multiple unit cells. Each unit cell includes multiple antenna elements configured to transmit or receive optical signals, where a first subset of the antenna elements is oriented in a first direction and a second subset of the antenna elements is oriented in a second direction opposite the first direction. Each unit cell also includes multiple signal pathways configured to transport the optical signals to or from the antenna elements, where at least some of the signal pathways have an 'H' configuration. Each unit cell further includes multiple phase modulators configured to modify phases of the optical signals being transported through the signal pathways.
